Guide on How to Build a Browser Game

Intro

Getting started and knowing how to structure the code in an application is one of the most difficult things for students to figure out.

Also, there might be plenty of sources available to learn about how to use a forEach loop, but finding help on how to think like a developer and write code to implement an app's features is difficult at best.

Let's Encrypt - Synology NAS + sameersbn/docker-gitlab

Getting HTTPS on a Synology NAS + Gitlab container is a bit tricky. Using self-assigned OpenSSL certificates is great, but it can only provide SSL certificates that inevitably will be flagged as untrusted by the browser due to the common name being unrecognized/not associated with a trusted SSL provider:

The downside will be that every user that remotely accesses your NAS will be greeted with the above message unless they manually add the certificate to their browser's approved SSL provider list. Instead, here's a work-around to enable HTTPS for both your Synology NAS and a Gitlab container using just one Let's Encrypt certification.

For more information regarding the docker-gitlab installation and set up: Synology Docker

1. Install acme.sh shell script

git clone https://github.com/Neilpang/acme.sh.git
cd acme.sh
./acme.sh --install

Optionally, set the home dir and/or account info (if already have one).
If was previously using LetsEncrypt's certbot, can probably get account info from /etc/letsencrypt/accounts/acme-v01.api.letsencrypt.org/directory/*/regr.json.
